TECHNICAL FIELD

The present technology is directed generally toward beverage container heating apparatuses and associated methods for using such apparatuses.

BACKGROUND

Drinking a hot beverage is an important part of life for many people. A hot cup of coffee is a regular, and often cherished, part of the morning for many. A warm bottle of baby formula is often a necessity for infants. Drinkware, such as cups, mugs, travel mugs, and baby bottles, is often used to hold hot liquids for the consumer until the liquid is ready to drink. A common issue with many existing drinkware is the inability to keep the beverage at a desired temperature for a long period of time. In some instances, for example, a beverage that is too hot for consumption is prepared and poured into the drinkware. In these situations, the consumer waits until the beverage has sufficiently cooled to a temperature that is safe to drink. However, if the consumer waits too long or prefers to drink the beverage slowly over a long period of time, the liquid may cool down too much, resulting in a beverage that is no longer satisfying (or even potentially dangerous in the case baby formula for infants).

Many types of drinkware are specifically designed to reduce the cooling rate of the hot liquid and to prolong the time over which the beverage cools enough to drink without the risk of burning, while remaining warm enough for a satisfactory drinking experience. These beverage containers are often formed from materials, such as ceramics or plastics, possessing insulative properties that aid in the temperature controlling process. While these materials may increase the time for which a beverage is safe and satisfying to drink, they are still incapable of maintaining the beverage at an elevated temperature for a prolonged period of time. Other types of drinkware, such as French presses made from glass or disposable coffee cups made from paper-based materials, possess few insulative properties and are subject to rapid cooling. It would therefore be desirable to develop a beverage warming apparatus that can be used in conjunction with existing drinkware to maintain the temperature of a liquid at a desired temperature for a prolonged period of time, ensuring that drinking the beverage remains safe and satisfying.

DETAILED DESCRIPTION

The following disclosure describes various aspects of beverage container heating apparatuses and associated methods for using such apparatuses. Certain details are set forth in the following description and in FIGS. 1A-8 to provide a thorough understanding of various embodiments of the technology. Well-known structures, systems and methods often associated with beverage containers and related apparatuses, however, have not been shown or described in detail below to avoid unnecessarily obscuring the description of the various embodiments of the present technology. Any dimensions, angles, and other specifications shown in the Figures are merely illustrative of particular embodiments of the technology. Accordingly, other embodiments of the technology can have other dimensions, angles, and specifications without departing from the spirit or scope of the present disclosure. In addition, those of ordinary skill in the relevant art will understand that additional embodiments of the technology may be practiced without several of the details described below.

FIG. 1A is a perspective view of a sleeve 100 (also known as “flexible band” and “flexible sleeve”) configured in accordance with an embodiment of the present technology arranged around a beverage container 102 (also known as “container”). The beverage container 102 is formed from a container body 104 (also known as “body”) and an inner cavity (not shown) within the container body 104 may be configured to receive and hold a beverage (not shown) for consumption by a user. The body 104 may also include an exterior surface 106 and the sleeve 100 is adapted to be circumferentially arranged around the exterior surface 106 such that an inner surface (not shown) of the sleeve 100 is in immediate contact with the exterior surface 106.

In the example shown in FIG. 1A, the beverage container 102 is a travel mug having a lid portion 108 releasably attached to the body 104. The use of a travel mug, however, is merely an example. In other embodiments, the sleeve 100 may be arranged around a variety of other suitable beverage containers, such as a baby bottle, a French press, a disposable cup having a lid, or other suitable containers. In still other embodiments, the sleeve 100 may be arranged around a beverage container 102 that does not include a lid, such as a mug or a cup. In general, the sleeve 100 may be arranged around any desired style/size/shape of beverage containers.

When the sleeve 100 is not arranged about the beverage container 102, the sleeve 100 may be a rectangular structure having a first end portion 112 a and a second end portion 112 b located at opposing ends of the rectangular structure. The sleeve 100 may be formed from a flexible and partially stretchable material capable of conforming to the exterior surface 106 of beverage containers 102 of many different sizes and styles. When the sleeve 100 is engaged with the exterior surface 106 of the beverage container 102, the sleeve 100 is configured for stretching to ensure that the first end portion 112 a and the second end portion 112 b at least partially overlap such that the sleeve 100 completely wraps about the exterior surface 106 of the beverage container 102.

For beverage containers 102 having an outer perimeter that is too large for the sleeve to completely surround, however, an optional gap 110 may be formed between the two end portions 112 a and 112 b. As will be discussed in greater detail in conjunction with FIGS. 5A-5C, the sleeve 100 may include a securing mechanism (not shown) to attach the first end portion 112 a to the second end portion 112 b when the sleeve 100 is arranged around the beverage container 102. In particular, when the sleeve 100 is wrapped around a large beverage container 102, the securing mechanism is configured to span the gap 110 to ensure that the first and second end portions 112 a, 112 b remain securely attached to each other and that the inner surface of the sleeve 100 maintains contact with the exterior surface 106. As noted previously, the sleeve 100 is adapted for stretching to fit around beverage containers 102 of many shapes and sizes (and may fit around many containers without forming of the gap 110). In these embodiments, the securing mechanism may not be required to ensure that the sleeve 100 remains securely engaged with the exterior surface 106 of the respective container.

FIG. 1B is a cross sectional view of the sleeve 100 of FIG. 1A when the sleeve 100 is positioned around the beverage container 102 (FIG. 1A). Referring to FIG. 1A and FIG. 1B together, the sleeve 100 in the illustrated embodiment includes an inner layer 114 configured to be arranged adjacent to the exterior surface 106 of the beverage container 102. The sleeve 100 also includes a middle layer 116 positioned adjacent to the inner layer 114 and an outer layer 118 positioned adjacent to the middle layer 114 such that the middle layer 116 is interposed between the inner layer 114 and the outer layer 118.

The inner layer 114 may include an inner, reflective surface 120 configured to be positioned adjacent to and facing the exterior surface 106 of the beverage container 102 when the sleeve 100 is wrapped around the container 102. As will be discussed in greater detail below, the reflective surface 120 is positioned to reflect heat coming off of the exterior surface 106 back towards the beverage container 102. The inner layer 114 may also include a heating element (not shown) arranged on the reflective surface 120 that is configured to generate and provide heat to the exterior surface 106 of the beverage container 102.

The middle layer 116 may be formed from an insulating material configured to absorb and store heat given off by the heating element in the inner layer 114 and/or heat given off by the beverage container 102 that does not get reflected back towards the beverage container 102 by the reflective surface 120. In some embodiments, the middle layer 116 may be permanently arranged between the inner layer 114 and the outer layer 118. In these embodiments, the insulating material may be a naturally occurring material (e.g., wool), a manmade material, and/or may be biodegradable. The insulating material may have a thermal resistance (i.e., an R-value) and a thickness that enables the sleeve 100 to maintain the temperature of the liquid held in the cavity of the beverage container 102 for a desired period of time without the use of the heating element included in the inner layer 114. It will be appreciated by those having ordinary skill in the art that the middle layer 116 may be composed of an insulating material having any desirable thermal resistance and thickness to maintain the temperature of a liquid retained within the beverage container 102 at or near a desired temperature for a desired period of time.

In other embodiments, the middle layer 116 may be a removable component that is slidably removable from the sleeve 100. As will be described in further detail below, the inner layer 114 and the outer layer 118 may be releasably coupled to each other along one edge of the sleeve 100 such that an opening is formed between the two layers. The middle layer 116 may be removably insertable into the opening and may be heatable using an external heating system when removed from the opening. In these embodiments, the insulating material may be a food safe material, may be a natural/vegetable-based material, may be sealed in a plastic wrapping, and/or may be waterproof. Further, in such embodiments the middle layer 116 may be composed of a material capable of being reheated a number of times using an external heating system.

Referring back to FIG. 1A, before beverage container 102 receives a liquid (not shown), the body 104 is typically at a lower temperature than the hot liquid. After the liquid is received within the body 104, the liquid exchanges heat with the body 104 to establish a thermal equilibrium between the body 104 and the liquid. As more heat is transferred into the body 104, the body 104 begins to heat up. The rate at which the temperature of the liquid and the temperature of the body 104 change is dependent on, among other things, the properties of the liquid (e.g., temperature, heat capacity, etc.), material properties of the body 104 (e.g., temperature, heat capacity, thermal conductivity, thermal resistance, thickness, etc.), and properties of the medium surrounding the exterior surface 106 of the beverage container 102 (e.g., air temperature). In situations where the exterior surface 106 of the beverage container 102 is completely exposed to the open air, the heat transferred from the hot liquid to the body 104 will be transferred to the air until the temperature of the hot liquid and the temperature of the body 104 are equal to the temperature of the air (if the beverage container 102 is left undisturbed). However, in situations where the sleeve 100 is arranged around the exterior 106 of the beverage container 102, the transference of heat from the hot liquid to the body 104 and from the body 104 to the air may be significantly slowed or stopped.

FIG. 2A is a schematic top view of a first embodiment of an inner layer 214 a of sleeve 200 a. The sleeve 200 a, for example, may include a number of features similar to or identical to the features of sleeve 100 and inner layer 114 of FIGS. 1A and 1B. Further, the sleeve 100 may include some or all of the features of the sleeves 200 a and 200 b described herein. The inner layer 214 a in the embodiment shown in FIG. 2A, for example, may include a reflective surface 220 a and a heating element 222 a. When the sleeve 200 a is arranged around a suitable beverage container (not shown), the inner layer 214 a is configured to be positioned in contact with an exterior surface of the container such that the reflective surface 220 a faces the exterior surface. The reflective surface 220 a, for example, may completely cover the entire inward-facing surface of the inner layer 214 a. In other embodiments, however, the reflective surface 220 a may only cover a portion of the surface of the inner layer 214 a.

When the sleeve 200 a is positioned on a container (e.g., container 102 of FIG. 1A), the reflective surface 220 a is configured to reflect at least some of the radiated heat from hot liquid within the container back toward an exterior surface of the container. By reflecting the heat, changes in temperature of the body of the container due to radiation of heat are expected to be reduced, thereby causing the temperature of the container body to remain at an elevated temperature for a longer period of time. As a result, changes in temperature between the hot liquid and the container body are also expected to be reduced. This is expected to result in the hot liquid remaining at an elevated temperature for a longer period of time, thus increasing the satisfaction of a consumer of the hot beverage.

While the reflective surface 220 a may prolong the time period at which the hot liquid remains at an elevated temperature, the temperature of the liquid may still eventually decrease to a temperature that is no longer satisfying for a consumer to drink. To help further prevent this temperature decrease from occurring, the inner layer 214 a may also include a heating element 222 a. The heating element 222 a, for example, may be a strip (or strips) of heat tape arranged adjacent in a desired pattern on the sleeve 200 a. In one embodiment, for example, the heat tape may be a polyamide flexible membrane heater film configured to generate heat and provide the generated heat to an exterior surface of a container to which the sleeve 200 a is attached. The heating element 222 a may be activated/controlled via a control signal from control circuitry and power from a power source. The heating element 222 a, for example, may be coupled to a battery (not shown) and various control circuitry (not shown) during formation of the sleeve 200 a itself. In some embodiments, the heating element 222 a may be arranged adjacent to the reflective surface 220 a such that the heating element 222 a is interposed between the exterior surface of the beverage container and the reflective surface 220 a when the sleeve is engaged with the container. It will be appreciated, however, that the arrangement shown in FIG. 2A is merely one example. In other embodiments, the heating element 222 a may be formed from heat foil or other suitable materials, and may have a variety of different arrangements on the sleeve 200 a. In general, the heating element 222 a may be formed from any desired flexible heating component capable of generating heat while the sleeve 200 a is wrapped about an exterior surface of a beverage container. By generating and providing additional heat to the corresponding exterior surface of a beverage container to which the sleeve 200 a is engaged, the heating element 222 a is expected to significantly extend the time period over which the hot liquid within the beverage container remains at an elevated temperature. More specifically, by generating and providing additional heat to the exterior surface, the amount of heat radiated from the exterior surface of the container may be offset by the heat provided to the exterior surface by the heating element 222 a. Because of this, the liquid and the body 104 may reach an equilibrium point where the amount of heat lost by the liquid (e.g., by transferring it into the body of the container or through evaporation of the liquid) is equal to the heat transferred to the liquid from the container body. In this way, the liquid may stay at or near a constant, elevated temperature for an extended period of time, substantially prolonging the time period for which consumption of the beverage is a satisfying experience for the user.

FIG. 2B is a schematic top view of a second embodiment an inner layer 214 b of a sleeve 200 b. In addition to the heating element 222 b and reflective surface 220 b, which are substantially equivalent to the heating element 222 a and the reflective surface 220 a described above in connection with FIG. 2A, the inner layer 214 b also includes a temperature sensor 224 and a pressure sensor 226. These components are both operably coupled to control circuitry located in the outer layer (not shown).

When the sleeve 200 b is arranged around the exterior surface of a suitable beverage container (e.g., beverage container 102 of FIG. 1A), the temperature sensor 224 and the pressure sensor 226 are positioned adjacent to the heating element 222 b such that the two sensors are interposed between the exterior surface of the beverage container and the reflective surface 220 b. The temperature sensor 224 is configured to measure the temperature of the exterior surface of the beverage container and provide the measured temperature to the control circuitry. As will be discussed in greater detail below, the sleeve 200 b is adapted to provide the measured temperature to a user of the sleeve 200 b so that the user may monitor the temperature the hot beverage.

As will be discussed in greater detail below, the sleeve 200 b may also use the temperature sensor 224 to automatically monitor the temperature of the exterior surface of the beverage container and the control circuitry may be programmed to activate the heating element 222 b when the measured temperature reaches or approaches a desired temperature. In this way, a beverage that is initially too hot for safe consumption may be allowed to cool to a desired temperature, at which point the heating element 222 b may be activated to maintain the temperature of the liquid at that desired temperature for an extended period of time.

Pressure sensor 226 may be configured to measure a pressure that is exerted upon the pressure sensor 226 and to provide the measured pressure to the control circuitry (not shown). For example, the pressure sensor 226 may be configured to record a first or initial pressure when the sleeve 200 b is not arranged around the beverage container 102 and a second, higher pressure when the sleeve 200 b is engaged with a beverage container. In this way, the pressure sensor 226 may function as an automatic power button such that the control circuitry may be configured to activate the control circuitry and powered components of the sleeve 200 b when the pressure sensor 226 determines that the sleeve 200 b is engaged with the beverage container, and likewise may turn the powered components of the sleeve 200 b off when the pressure sensor 226 determines that the sleeve 200 b is no longer engaged with the beverage container.

The use of temperature sensor 224 and pressure sensor 226, however, is optional. In some embodiments, for example, the inner layer 214 b may include only the temperature sensor 224, may include only the pressure sensor 226, may include a different sensor, or any combination thereof. In general, inner layer 214 b may include any desired combination of sensor(s).

FIG. 3 is a perspective view of the sleeve 100 of FIGS. 1A and 1B with the removable middle layer 116 partially removed from the sleeve 100. Referring to FIGS. 1A, 1B, and 3 together, as previously mentioned, the inner layer 114 and the outer layer 118 may be releasably coupled to each other along a top edge 128 a, such that the two layers form an opening configured to receive the removable middle layer 116. The middle layer 116 may be formed from an insulating material heatable using an external heating element, such as a microwave or hot water bath. When the sleeve 100 is to be used to keep a beverage at an elevated temperature for a long period of time, a user may remove the middle layer 116 from the sleeve 100, heat up the middle layer 116 using an external heating element, reinsert the middle layer 116 into the sleeve 100, and then arrange the sleeve 100 around the exterior surface 106 of a beverage container 102. The warmed insulation material acts as a second heat source by providing additional heat to the exterior surface 106 of the beverage container 102, and reduces the amount of heat transferred from the body 104 of the beverage container 102 to the sleeve 100. The removable insulating material may therefore be used to further prolong the time period for which a hot beverage within a beverage container stays at a desired temperature.

The inner layer 114 and the outer layer 118 may each be formed from rectilinear structures having top, left, bottom, and right edges. During construction of the sleeve 100, the left, bottom, and right edges of the inner layer 114 may each be coupled to the respective left, bottom, and right edges of the outer layer 118 using a fixed or permanent attachment mechanism (e.g., sewing the edges together, applying an adhesive along the edges, etc.). The coupled or fixed edges of the inner layer 114 and the outer layer 118 form the left edge 128 b, bottom edge 128 c, and right edge 128 d of the sleeve 100. The top edge of the inner layer 114 may be coupled to the top edge of the outer layer 118 using a releasable attachment mechanism (e.g., a zipper, snaps, hook and loop apparatus, etc.). The releasably coupled edges of the inner layer 114 and the outer layer 118 form the top edge 128 a.

When the top edge 128 a of the sleeve 100 is opened (i.e., the releasable attachment mechanism is disengaged and the top edge of the inner layer 114 is separated from the top edge of the outer layer 118), an opening may be formed between the inner layer 114 and the outer layer 118. In this arrangement, the sleeve 100 includes a pouch-like structure and the opening may be configured to receive the removable middle layer 116. In the embodiment shown in FIG. 3, for example, the middle layer 116 is shown partially removed from the opening such that a top edge 130 of the middle layer 116 is positioned over the top edge 128 a of the sleeve 100 and is no longer enclosed within the opening between the inner layer 114 and the outer layer 118. If desired, a user of the sleeve may continue to remove the middle layer 116 from the opening until a bottom edge (not shown) of the middle layer 116 is no longer positioned within the opening. At his point, the user may use an external heat source, such as a microwave or a hot water bath, to heat the middle layer 116 to a desired temperature. After being heated, the middle layer 116 may then be reinserted into the opening such that the entirety of the middle layer 116 is enclosed within the opening and the top edge 130 of the middle layer 116 is positioned below the top edge 128 a of the sleeve 100. The releasable enclosure mechanism may then be used to secure the top edge of the inner layer 114 to the top edge of the outer layer 118 and the sleeve 100 can then be releasably secured about the exterior surface 106 of the beverage container 102.

The middle layer 116 may be formed, for example, from an insulating material configured to absorb and retain heat given off by the heating elements (not shown) in the inner layer 114, heat given off by the beverage container 102 that does not get reflected back towards the beverage container by the reflective surface (not shown) of the inner layer 114, and/or heat provided to the middle layer 116 by an external heating system. The insulating material may have a thermal resistance (i.e., an R-value) and a thickness designed to allow the sleeve 100 to maintain the temperature of the liquid retained within the beverage container 102 for a period of time without the use of a powered heating element included in the inner layer 114. The insulating material may also be a food safe material to ensure that exposure of the middle layer 116 to external heating mechanisms that may also be used to prepare food (e.g., a microwave) or direct exposure to a user of the sleeve 100 handling the middle layer 116 does not result in the transference of harmful contaminants to the external heating mechanism or the user. In some embodiments, the insulating material may be formed from a natural, vegetable-based, and/or biodegradable material that allows a consumer to purchase a replacement middle layer 116 in the event that the original middle layer 116 is damaged or no longer usable without worrying about the environmental impact of purchasing such a replacement. In other embodiments, however, the insulating material may be composed of different suitable materials. In general, the middle layer 116 may be formed from any desirable material capable of being heated using an external heating system when the middle layer 116 is removed from the sleeve 100.

FIG. 4 is a schematic view of an outer layer 418 of a sleeve 400 configured in accordance with an embodiment of the present technology. The sleeve 400 (like sleeves 200 a and 200 b described above) may include a number of features similar to or identical to the features of sleeve 100 of FIGS. 1A and 1B. Further, the sleeve 100 may include some or all of the features of the sleeve 400 described below. As best seen in FIG. 4, the sleeve 400 comprises a plurality of electrical components. The components may include, for example, a processor 432, at least one sensor 434, a power source 436, a light source 438, a transceiver 440, an image sensor 442, a display 444, and/or a stabilizer 446. The components of the outer layer 418 are configured to enhance functionality of the sleeve 400 when the sleeve 400 is arranged around a suitable beverage container.

The processor 432 (also known as “control circuit”) can be electrically coupled to the heating element, temperature sensor, and pressure sensor(s) included in an inner layer (not shown) of the sleeve 400. In some embodiments, for example, the sleeve 400 may include an inner layer and/or a middle layer including some or all of the features of sleeves 200 a and 200 b described above with reference to FIGS. 2A and 2B. For example, when the sleeve 400 is arranged around a beverage container and is being used to insulate and provide heat to the container, the temperature sensor and pressure sensor provide temperature and pressure measurements to the processor 432. The processor 432 may include a memory circuit configured to store predetermined values (e.g., predetermined temperatures and pressures) and the processor may be configured to compare the measurements from the sensors to the predetermined temperatures and pressures to change the operating mode of the sleeve 400. As previously discussed, the processor 432 may be configured to turn the sleeve 400 on when the pressure measured by the pressure sensor changes from a first pressure (i.e., the beverage container 102 is not pressing against the pressure sensor) to a second, different pressure (i.e., the beverage container 102 is pressing against the sensor), and may be configured to turn the sleeve off when the pressure measured by the pressure sensor changes from the second pressure to the first pressure or a third, different pressure less than the second pressure. In other embodiments, it will also be appreciated that the sleeve 400 may include inner and middle layers (not shown) having different components and/or features.

The processor 432 may also be configured to adjust the amount of heat produced by a heating element, such as heating elements 222 a and 222 b of FIGS. 2A and 2B, based on the temperature measured by a temperature sensor included in the inner layer. As previously discussed, when a hot liquid is first received within beverage container 102, the temperature of the exterior surface 106 of the beverage container 102 may increase. A temperature sensor coupled to the processor 432 and arranged against the exterior surface 106 can be configured to measure the temperature of the exterior surface 106 and provide the measured temperature to the processor 432. Without using a heating element to provide more heat to the beverage container 102, the temperature of the container and, therefore, the liquid will cool. As it cools, the temperature sensor may continue to measure and report the temperature of the exterior surface 106 to processor 432, which may compare the temperature measurements to a predetermined temperature.

When the measured temperature reaches the predetermined temperature, the processor 432 can be configured to send a control signal to a heating element, turning the heating element on so that it begins to provide head to the beverage container 102. The processor 432 may continue to receive temperature measurements from the temperature sensor while the heating element provides heat to the exterior surface 106. If the temperature measurements continue to decrease past the predetermined temperature, the processor 432 may adjust the control signal sent to the heating element so that the heating element increases the amount of heat provided to the beverage container 102. If the temperature begins to increase to an unsafe temperature or a temperature that may cause an unsatisfactory experience for the consumer, the processor 432 can be configured to change the control signal sent to the heating element such that the heating element decreases the amount of heat provided to the beverage container 102.

The processor 432 may also be coupled to a power source 436 configured to store and provide power to the other electrical components of the sleeve 400. The power source 436, for example, may be a battery configured to be replaced when all of the stored power is used or it may be a rechargeable battery. In embodiments where the power source 436 comprises a rechargeable battery, the sleeve 400 may also include a port configured to receive a power cord or may include a wireless charging apparatus adapted to recharge the battery. However, the use of a power source 436 to power the electrical components of the sleeve 400 is merely an example. In other embodiments, the sleeve 400 may include a port configured to receive a power cord such that the sleeve 400 receives power directly from the power cord. It is appreciated that one of ordinary skill in the art may incorporate a variety of types of power sources to provide power to the electrical components of the sleeve 400.

The outer layer 418 may also include at least one sensor 434 coupled to the processor 432. The processor 432 is configured to change the state of the sleeve 400 based on one or more measurements recorded by the sensor(s) 434. In some embodiments, for example, the sensor 434 may be a fingerprint sensor arranged on an exterior surface of the outer layer 418. The fingerprint sensor may be configured to capture an image of a user's finger when the user positions her/his finger on top of the fingerprint sensor. The image may be provided to the processor 432, which is configured to compare the captured fingerprint image to a predetermined fingerprint image by calculating a difference between the captured fingerprint image and the predetermined fingerprint image. If the calculated difference is less than a predetermined difference threshold, the processor 432 may determine that finger positioned over the fingerprint sensor belongs to the owner of the sleeve 400 and the processor 432 can be configured to transition the sleeve 400 to a desired state. If the calculated difference is greater than the predetermined threshold, the processor 432 may determine that the finger positioned over the sensor belongs to someone other than the owner of the sleeve 400 and the processor 432 can be configured to transition the sleeve to a powerless state.

In other embodiments, the sensor(s) 434 may include other suitable types of sensors in addition to, or in lieu of, the fingerprint sensor. For example, in some embodiments the sensor 434 may include a global positioning sensor (GPS) configured to track the location of the sleeve 400 in the event that the location of the sleeve 400 is unknown to the owner. The sensor 434 may also include one or more accelerometers configured to measure the orientation of the beverage container 102 and may be configured to detect if the beverage container 102 is not oriented properly. In general, the outer layer 418 of the sleeve 400 may include any desired number or types of sensors configured to measure various desired characteristics of the sleeve 400, the beverage container 102, a user of the sleeve 400, and/or the external environment.

In some embodiments, the outer layer 418 may also include a light source 438 positioned on an exterior surface of the outer layer 418 to communicate a current status of the sleeve 400 and/or a beverage within the container 102. In some embodiments, for example, the light source 438 may be configured to turn on when the sleeve 400 is in a powered state and turn off when the sleeve 400 is in a powerless state. The light source 438 may also be configured to have a variable brightness and/or color to convey a status regarding the temperature of the beverage within the beverage container 102 and/or the amount of power remaining within the power source 436. In situations where the sleeve 400 is utilized in a retail environment, the light source 438 may be used, for example, to convey that the container needs a refill. In other embodiments, the light source 438 may be used as a mood indicator or may be used to illuminate a feature on the exterior surface of the sleeve 400, such as a logo. In additional embodiments, the outer layer 418 may include any desired number of light sources 438 and each light source 438 may perform one or more functions.

In some embodiments, the outer sleeve 418 may also include a transceiver 440 operably coupled to the processor 432 and configured to establish a wireless connection between the processor 432 and one or more external control devices (e.g., a cell phone—not shown). The transceiver 440, for example, may be configured to receive a status signal from the processor 432 and transmit the received status signal to the external control device over the established wireless connection. In some embodiments, the status signal may include a temperature measurement collected by the temperature sensor included with the inner layer of the sleeve 400, and/or the status signal may include information from the power source 436 indicating the amount of power remaining within the power source 436. The status signal, for example, may be displayed by an application on the external control device so that the user of the external control device can review the status signal remotely.

In some embodiments, the transceiver 440 may also be configured to receive a control signal from the external control device. A user of an external control device connected to the sleeve 440 over a wireless connection, for example, may use an application on the external control device to set a desired temperature for the liquid within the beverage container 102. The external control device may also generate a control signal that includes the desired temperature and may transmit the control signal over the wireless connection. The transceiver 440 may be further configured to receive the control signal and provide the received signal (or the desired temperature) to the processor 432, which may then adjust the amount of heat provided to the beverage container 102 based on the desired temperature. This, however, is merely an example. In other embodiments, the transceiver 440 may be configured to receive an “On” (or “Off”) signal generated by an external control device and the processor 432 may be configured to transition the sleeve 400 to a powered-on state (or powered-off state), respectively, in response to receiving the signal from the external control device. In general, the transceiver 440 may be configured to receive any desired signal from the external control device.

The transceiver 440 may be further configured to establish a wireless connection using any desired wireless communication scheme. In some embodiments, for example, the transceiver 440 may be a Bluetooth transceiver configured to communicate with an external communication device using a Bluetooth connection. In other embodiments, the transceiver 440 may be a Wi-Fi transceiver configured to communicate with the external communication device using a Wi-Fi connection. It will be appreciated that one of ordinary skill in the art may replace the transceiver 440 with any desired type of transceiver such that the transceiver is capable of forming a wireless connection with one or more external control devices using any desired wireless communication scheme.

In some embodiments, the outer layer 418 may also include an image sensor 442 configured to capture images or videos. The image sensor 442 may function as a secondary camera for an external control device wirelessly connected to the image sensor 442 using the transceiver 440 or may be used as a stand-alone image sensor.

A display 444 may be arranged along the exterior surface of the outer layer 418 and adapted to display a status of the sleeve 400, such as the battery life, or a status of the liquid within the beverage container 102, such as the temperature measured by a temperature sensor. In some embodiments, for example, the display 444 may be coupled to the image sensor 442 and configured to display images and/or videos captured by the image sensor. In other embodiments, the display 444 may be used to display a logo. The display 444 may be a flexible display capable of conforming to the curved surface of the outer layer 418 when the sleeve 400 is arranged around a beverage container having a curved exterior surface.

In still other embodiments, the outer layer 418 may also include a stabilizer 446 (e.g., a gyroscope) configured to prevent the beverage container from accidentally tipping over when the sleeve 400 is attached thereto. Additional electrical components, such as a speaker, may also be included in the outer layer 418.

The use of five finger sleeves 656 a-e, however, is merely an example. In other embodiments, the gripping mechanism 654 may include fewer than five finger sleeves. For example, in embodiments that only include four finger sleeves, the gripping mechanism 654 may not include a finger sleeve 656 a positioned to receive a user's thumb 658 a and may only include the finger sleeves 656 b-e each positioned to receive a respective one of the user's fingers 658 b-e. In other embodiments, gripping mechanism 654 may include finger sleeves positioned to receive more than one finger. For example, the gripping mechanism 654 may include a first finger sleeve 656 a positioned to receive a user's thumb 658 a, a second finger sleeve 656 b positioned to receive the user's pointer finger 658 b and middle finger 658 c, and a third finger sleeve 656 c positioned to receive the user's ring finger 658 d and pinkie finger 658 e. In general, the gripping mechanism 654 may include any desired number of finger sleeves 656 that may be positioned around the exterior surface of the sleeve 600 in any desired position so that the sleeves 656 may each receive any desired number of fingers 658.

Each finger sleeve 656 may be formed from a flexible material. In some embodiments, for example, the material may be an insulating material configured to keep the fingers 658 at a comfortable temperature, regardless of the temperature of the air surrounding the sleeve 600. In other embodiments, however, the finger sleeves 656 may be composed of different materials and/or have a different arrangement.

As previously discussed in connection with the embodiment shown in FIG. 4, the outer layer 618 of the sleeve 600 may include a fingerprint sensor 634.
